Data compaction is supported for the to volume on the Duplicate Media using BRM (DUPMEDBRM
) command.
In releases IBM i 6.1 and later, the Data compaction (COMPACT) parameter on the DUPMEDBRM
command can be used to indicate whether to use data compaction on the to volume.
Notes:
DUPMEDBRM
command default to *YES for the Compact parameter, the behavior can be acquired.In release V5R4M0, these commands can be used to create data area Q1ADUPCOMP
to indicate whether to use data compaction on the to volume:
This would cause *YES behavior (which is desired on the TS7650 to physical 3584 tape)
CRTDTAARA DTAARA(QTEMP/Q1ADUPCOMP) TYPE(*CHAR) LEN(9) VALUE('*YES')
This would cause *NO behavior:
CRTDTAARA DTAARA(QTEMP/Q1ADUPCOMP) TYPE(*CHAR) LEN(9) VALUE('*NO')
This would cause the current behavior (i.e. if the data area did not exist):
CRTDTAARA DTAARA(QTEMP/Q1ADUPCOMP) TYPE(*CHAR) LEN(9) VALUE('*FROMFILE')
NOTES:
DUPMEDBRM
command. If the DUPMEDBRM
command is run in batch, the data area must also be created in library QTEMP for the batch job.
